JAMES J. SULLIVAN, OF LONG ISLAND CITY, NEWV YORK.

WRAPPING-MACHINE.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed October 5, 1905. Serial No. 281,457.

To all whom it Wtay concern:

Be it known that I, JAMEs J. SULLIVAN, a citizen of the United States of America, and a resident of Long Island City, county of Queens, State of New York, have invented certain new and useful Improvements in Wrapping-Machines,- of which the, following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to machines for automatically wrapping articles with a suitable material, such as leador tin-foil, and for applying and securing a label thereto.

The main object of my invention is to provide a small, simple, compact and light running machine for this purpose, whereby the same will be inexpensive to build, will occupy but small space, and will be capable of a high speed of operation.

In carrying out my invention I provide means for operating simultaneously on several articles in successive stages in the machine, whereby a considerable saving of time is effected; and I arrange the several mechanisms in groups, whereby the various parts of the machine may be readily reached for purposes of cleaning or repair without it being necessary to dismantle the machine piecemeal.

It is a further object to reduce to a minimum the distance of travel of the various working parts, so as to avoid undue friction and wear, and reduce shock due to momentum and inertia.

I also aim to fold the wrapper in such a way as to effectually seal the article contained therein, the ends of the wrapper being folded over, and then tucked under, to be finally permanently secured in position by the label.

To these various ends, my invention consists in many novel details of construction and combinationof parts, some of them radically new in themselves, and others in their combination and modes of operation, all as will be clearly set forth hereinafter.

In order that my invention may be fully understood, I willdescribe in detail a machine embodying my invention, having reference to the accompanying drawings illustrating same, and will then point out the novel features in claims.

Figure 1 is a view in side elevation of a machine embodying my invention: Fig. 2 is a view in central vertical longitudinal section therethrough. Fig. 3 is a top view with the overhead parts removed. Fig. 4 is a view in vertical section upon the plane of the line 4 4 of Fig. 3, showing the machine substantially in rear elevation, but with certain of the overhead parts removed. Fig. 5 is a view in vertical transverse section upon the plane of the line 5-5 of Fig. 2. Fig. 6 is a view in vertical transverse section upon the line 6-6 of Fig. 2. Fig. 7 is a detail view showing an under side view of the main reciprocating plate and certain correlated parts. Fig. 8 is a detail view showing certain connections for the delivery mechanism. Fig. 9 is a detail view of the knife or cutter for the wrapper, and certain parts of the knife operating mechanism. Fig. 10 is a detail view of a finger or steadying device employed in connection therewith. Fig. 11 is a detail sectional view of certain parts upon the line 11-11 of Fig. 2. Fig. 12 is a detail view in perspective of a folding plate employed. Figs.13, 14,15, 16, 17, 18, 19, 20, 21, 22 and 23 are diagrammatic views showing the operation of wrapping an article. Fig. 24 is a view in perspective of an article with the first wrapper completely finished, but before the label is put on.

The particular machine illustrated in the accompanying drawings is designed for the purpose of wrapping pieces of chocolate with lead foil, and afterward affixing a second wrapper, which constitutes a label, and which I will here refer to as a label.

It will be of course understood that the machine is adapted for wrapping other articles, and that such articles may be wrapped with other material, and that the particular description herein is intended for the purpose of describing the present machine, and is in no way intended to be a limitation on the specific construction, form or adaptability of the apparatus.

In the machine herein, a frame 1 serves as a support for the various parts, including the main drive shaft 2 which is journaled in stationary bearings upon the machine, and is arranged transversely of the machine at about the middle thereof. This shaft is driven from a suitable source, not shown, through gearing 3, and carries the main cams and other devices which operate the moving parts of the machine. One of these devices com rises a mutilated gear-wheel 4, having teet throughout approximately one half of its circumference, and a plain portion IIO throughout the other half of its circumference. This mutilated gear-wheel is arranged to engage with mutilated pinions 5 and 6 ar ranged, respectively, upon stub shafts 7 and 8, each of said pinions arranged to be given one complete rotationduring one half of the rotation of the gear 4, and to remain at rest during the other half of the rotation. of the said gear-wheel.

Mounted upon the stub shaft 7, and secured fast to the pinion 5, is a crank arm 9, which carries a crank pin 10 connected by means of a pitman 11 with a depending bracket 12 from the main. reciprocating plate 13. Mounted upon the stub shaft 8 is a crank arm 14, which is secured fast to the pinion 6, and which carries a crank pin 15 to which is connected a pitman 16. The pitman at its other end (see more particularly Figs. 2, 4 and 5) is connected to an arm 17, in turn secured by a pin 18 to a cross head 19. The cross head 19 is secured fast upon a vertical plunger rod 20, which carries at its upper end the overhead portions of the machine. Intermediate its ends the said plunger 20 is mounted in, and guided by, a vertical standard'21 secured. to, or formed as a part of, the main frame of the machine. The cross head extends laterally toward the op posite side of the machine, and carries two anti-friction guide rollers 22, which engage with a vertical guide-way 23. The guideway 23 and rollers 22 form vertical bearings for the cross head 19 to maintain the parts in proper relative positions as they are reciprocated by rotation of the crank arm 14. The main reciprocating member or plate 13 is arranged to slide in suitable ways 24 (see particularly Fig. 6), formed as a part of, or secured to, the frame 1, the reciprocation thereof being effected by rotation of the mutilated pinion. 5 and crank arm 7 as aforesaid. A stationary top plate 25 is arranged immediately above the upper face of the plate 13, said stationary plate 25 being secured to, or formed as a part of, the said frame. This plate is provided longitudinally with a central slot 26, in which is fitted a bar 27, constituting a carrying member, as will hereinafter appear. This carrying member is secured by means of screws 28 to the reciprocating plate 13, the upper face of the said bar being about level with the upper face of the stationary top plate 25. The reciprocating plate 13 also carries with it an overhanging pusher plate 29, secured by screws 30 to laterally extending portions 31 of the said reciprocating plate 13, the said pusher plate overhanging the stationary top plate 25 and the bar 27, as will be clearly seen by reference to Figs. 3 and 6. The reciprocating plate 13 further carries a bar 32 secured beneath its lower face by means of screws 33, the outer end of said. bar provided with an upwardly projecting portion 34 constituting the stationary member or jaw of a gripper. that is to say, a gripper member statimiary upon the reciprocating plate. A movable bar is mounted between the lower face of the plate 13 and the said stationary gripper bar 32, said movable grii 'iper bar having a limited. longitudinal movement with relation to saidv plate 13 and stationary gripper bar 32, said bar 35 being slotted at the portion sur' rounding the screws 30 to permit of said limited movement. At its forward end the said movable gripper bar 35 supports and carries a pivoted gripping jaw 36, the same being pivoted thereon, and having :1. depending lii'iger 37 which engages an opening in the stationary gripper bar 32, as will be clearly understood by reference to Fig. 2 of the drawings. At its rear end the movable gripper bar carries a small plunger 38, which or ters a cylindrical opening 39 in the bracket 12 and engages a compression spring 40 contained therein. The said coi'npression spring normally tends to force the movable bar 35 forward with respect to the stationary bar 3' to tightly close the ripping jaws 34 and 3' Pivotally supported. against the under face of the stationary bar 32 a cam piece 41, and, secured to the movable bar 35 by means of a stud 42, the shank of which passes through a slot in. the stationary bar, is a follower roller 43. The camv piece 41 has two notches 44 and 45, each of which is adapted to engage the follower roller 43. The notch is, however, at a greater distance from the pivotal center of the cam piece 41 than is t he notch 44. When the follower roller 42 is resting in the notch 43 of the cam piece 41, the movable bar 35 will be in its relaxed or forward position with respect to the stationary bar 32, and in. this position the gripper jaws 34 and 36 will be closed. When, however, the follower roller 43 is in engagement with the notch 45 of the camv piece 41, the bar 35 will be in. its rearward position with respect to the bar 32, and the movable jaw 36 will have been swung open. upon its pivot. A portion of the two bars 32 and 35 are shown in the latter position in Fig. 19, the movable jaw 36 being shown as swung open with respect to the stationary jaw 34.

In order that the cam piece 41 ma y be operated, it is provided with a lateral e;\'%ension or arm 46, in the path. of inovomenl of which is a *anged a stationary abutment 47 secured. to the framework 1. 11s the plate 13 and parts carried. thereby move forward the arm 46 is engaged. by the stationary abutment 47 to throw the cam piece 41 from a position with. its notch 45 in engagement with. the roller 43, to a position with its notch 44 in such engagement, in which latter position the parts are shown in Fig. 7. The engagement of the arm 46 withv the abutment 47 will. be at substantially the termination of the forward movement of the said plate and parts carried thereby, whereby the grippers will be snapped shut at just about .the completion of such movement. The parts will be held in this position by means of the spring 40 during the rearward movement of the plate and until the cam piece 41 is en gaged by a finger 48, carried by a lever e9 mounted upon a shaft 50. A cam 51 upon the main shaft 2 engages a follower roller 52 carried by a lever 53, which is also secured to the rock shaft 50, and the said cam 51, in its rotation, will effect the rocking of the shaft 50 to vibrate-the lever 49, and thus to cause the finger 48 to engage the lateral arm 46 of the cam 41 at the required moment. A spring 54, secured at one end to the frame, and at the other end to the lever 49, serves as a yielding pressure device to hold the cam follower up in engagement with the face of its cam.

In addition to carrying the finger piece 48-, the lever 419 engages a yoke piece which projects downward from a sliding folder plate 56. This plate 56 is mounted to slide in ways in the frame of the machine, and has a portion which extends upward, forward and latorally in front of the forward end'of the top plate 25, as will be seen in Figs. 2 and .12. The vibration of the lever 49, as above set forth, will effect a reciprocation of the folder plate 56 for the purpose of accomplishing the first fold of the wrapper, as will be presently explained, the plate 56 being shown in its rearmost position in Fig. 2, and as having 'moved forward in Fig. 15.

The wrapping material, which, in the present instance, is lead foil, as shown at 57 in the drawings, is supplied from a reel or other source, not shown, the forward end thereof passing over a direction roller 58, thence over the face of the top plate 25 and bar 27, beneath the overhanging pusher plate 29, to a point at about opposite the line 20, Figs. 1, 2 and 3 of the drawings. As before stated, the bar 27 constitutes a carrymg member for the wrapping material, and, acting in conjunction with this carrying member, is a clamping finger 59. This clamping finger is secured to a hub 60 mounted to slide upon a rectangular rock shaft or bar 61, itself mounted to rock in bearings 62 upon the main frame of the machine.

A spring 63 coiled about one end of the shaft, tends to rock the same in one direction, causing the finger 59 to normally bear with a yielding pressure toward the bar 27 The said hub 60 is provided. with a handle or hand piece 64, by which the shaft may be rocked and the finger thrown upward when desired, as in first threading up the machine. For the purpose of rocking this shaft during the normal operation of the machine, I have provided the same with a segment of a gear 65, which is arranged in mesh with a gear sector 66, constituting one portion of a bell crank lever, the other arm 67 of which car ries a cam follower roller 68. This roller is arranged to beengaged by a crown cam 69 disposed upon the face of the mutilated gearwheel 1. The action of the cam will rock the bell crank lever 66, 67 upon its support to cause the rocking of the shaft 61 and the lifting of the finger 59. The said cam will be so timed with relation to the reciprocating movement of the plate that the finger will be so lifted during the rearward movement of the plate, and will be left free to clamp the wrapping material between itself and the bar 27 during the forward movement of the plate. The clamping finger 59 and the carrier bar 27 will then act as a feeding device to intermittently feed the wrapping material forward step by step upon the re-. ciprocation of the main reciprocating plate 1 3. Resting upon the top of the plate 25, near the rear thereof, is a retarding or checking device comprising a finger 70 formed by bending a lever 71 at right-angles to itself, said lever pivoted at 72 to the frame of the machine. The lever 71 carries a roller 73, which rests upon a cam 74 secured to, and carried by, the plate 13. During certain parts of the movement of the plate 13, the cam 74 will lift the lever 71 and the finger 70, while, during other parts of its movement, it will allow the said finger to rest upon the wrapper, permitting it to act at such times as a retarding or checking device.

Arranged immediately above the top plate and the carrying bar 27, at a point just in advance of the front of the pusher plate 29 when the said. plate is in its rearmost position, is a magazine 75 for the articles to be wrapped. These articles may be arranged loosely in the said magazine, the lowermost article resting upon the wrapping material upon the carrying plate 27. Vi hen the plate 13 is given a forward movement to feed the wrapping material forward, the lowermost article beneath the magazine is also fed forward by engagement with the front face of the pusher 29, and the amount of such movement will be sufficient to bring the said article immediately beneath a plunger 76 and above a vertical supporting device 77. The supporting device 77 comprises a stem 73 mounted to slide in a bearing 79, and a bifurcated or forked portion 80 guided in bearings 81, said portions bifurcated or forked in order to straddle the bars 32 and 35. A spring 82 resists downward movement of the device, but permits such downward movement under yielding pressure. When in its uppermost position the top edges of the forked portion 80 are about level with the upper surface of the top plate 25 and of the upper surface of the bar 27, but at a point a little in advance of the forward ends thereof,

so that the wrapper and. article resting therewith a pin 90 (see Fig. 10), which reeei'ved on may be received hy the said supporting device as they are fed forward.

Located at a point just in advance of the finger 59, and between the said finger and the path of movement of the plunger 76, a severing device for the wrapper and. a yielding device for steadving the portion of the wrapper so severed. The severing device comprises a lelade 83 carried by a lever pivotally mounted upon a spindle and. a housing or shroud as. This device is she. n in detail in Fig. 9, and appears also clearly in Figs. 3 and 14:. The shroud. is loosely ()0 pivoted upon a spindle S5, and is connected with the lever 8 1 by means of a yieldin eonnection 87, as clearly shown in l 0. The severing device is operated by means of a cam upon the main shaft 1?, said eam 8S engaging a cam roller carried by an arm. upon a vertically reciprocating spindle 91.

The spindle 91 is mounted to move in stationary bearings 92, and is normally pressed downward to keep the roller 89 against the face of the cam 88 hy means of a compression spring 93. A link connects the arm 90 with the lever 84, the verti;al movement of reciprocation of the said arm 90 inmarling thereby a rocking movement of the lever 8% upon the spindle The (am 88 so timed with relation to the feed for the wrapping material that the severing device will descend to sever a portion of the material during the time the material is at rest after a 1 step by step forward movement. The llado 83 and housing 86 are so relatively arrai'iged. that the housing 86 will rest upon the wrap ping material before the l:lade commences to cut. This will have the effect of steadving the wrapping material and holding the same while the blade does the severing. Further, a noteh 95 is preferahly provided. in the top plate 25 and. bar 27 for receiving the severing edge of the blade so as to insure the complete severance of the material, and the action of the housing or shroud will ire to prevent the blade from earrvin g the material down into the notch, as will he well understood. In order to steady the piece of wrapping material which has keen severed, l have provided a memlter 96 having a liifur. ated or forked portion comprising two fingers 07, 97, arranged to straddle the supporting de-- vice 77 and. to rest upon the severed portion of material at points upon opposite sides of the path of movement of the plunger 76. This steadying memher 96 is pivotally mounted upon the spindle 85 which carries the severing devise, and a spring 98 tends to forte the said fingers dowrnvard to press upon the wrapping material with a yielding pressure. The spindle 85 is secured fast to the lever 8- of the cutter devire, and therefore rocks with the said lever, and this spindle is provided l l i l l l in a slot 100 in the huh of the memlrer 06. The slot 100 permits a certain amount of lost motion between the spindle 85 and the memher 96, hut the spindle 85, in its rwliing movement, finally lifts the steadying devi-e 96 at the proper moment when it is desired to feed the fresh piece of n'iaterial li-(Piltillll same.

After the piece of the wrapping i'nalerial whieh extends l; ond the knife l lade st: has heen severed therefh v, the plunger 7 6 is moved downward. to engage the arti. le rest ing thereon and. upon the srmpmting device 77, so as to fore the article down through an opening 101, and, at the same time, for ing the supporting device 77 downward against the resistance of the spring 82. The head of the plunger 76 is forked or lxifu 1K ated, as will lte seen more particularly l:- v referen e to Fig. 5, it lteing provided with shouldered portions 102 adapted to engage the arti lo lo re wrapped near the ends thereof, as the plunger desaends. The plunger 76 is i arried by a head 1 03, \Vllln ll is in turn me unted u pen. and carried hv, the plunger rod 20, so that re iprotation of the plunger head 76 will he effected by reciprocation of the plunger rod 30 lzy the means and in themanner al'ove so: forth. i. prefer to provide for aslight viel l ing lmt'ween the plunger head 76 and the supporl ing head 103 to prevent undue shoz-lc upon the edges of the artirle to he wrapped, the present construction for this purpose comprising a square stem 1041 mounted lo slide in the head 103, with small compression springs 105 arranged. hetween the said head 103 and a shoulder upon the stem. The square stem will prevent the plunger from turning while permitting relative 'verl it al movement, and the springs will yieldlugly resist sueh vertical movement.

In order to prevent damage to the parts in case the machine should operate without an article lreing heneath the plunger 76, wherehy the plunger 76 will fail to depress the supporting deviee 77, l. have provided auxiliary means which will compel the depression of the said plunger, comprising a lever 106 socured to the rock shaft 50 and arranged to engage an alzutment 107 carried lxy the stem 78 of the supporting devise 77 (see parli:-u larly Figs 1, 2 and 6). The shaft 50, it will he rememl'zemd, is caused to rock l: v means of the cam 51, and the said ram is timed to operate at such a period in the cycle of 'lhe ma hine as to depress the deviee in case If it shall not have lzeen depressed lwv thenou mal means, in time to move same oul ol the path of the reciproeating plate 13 and parts carried therehyx The opening 101, ahove referred to. is a.r-- ranged. hetween the forward end of th lop plate 25 and the rear end of a presser plate 108, the said presser plate 108 being a hori- Zontal plate provided with arms 109 arranged to bound the ends of the said opening 101 and to form means by which the said. presser plate may be pivoted to the said top plate 25. Near its outer end the plate carries a vertical plunger 110, which enters a housing 111 secured to the pedestal 21, and containing a compression spring 112. The spring 112 tends to force the presser plate downward with a yielding pressure, but forms a resisting device against which the plate may be forced upward.

When the plunger 76 has been moved downward to force the article resting beneath it upon the supporting device 77 downward through the opening 101, the severed portion of wrapping material will have its sides forced upward against the sides of the article, the article being forced downward to a position wherein its upper face is about in line with the under faces of the sliding folding plate 56 and of the presser plate 108. While it is held in this position, the folder plate 56 is moved forward to the position about as shown in Fig. 15. After this has taken place the plate 13 will move forward, the forward end of same engaging the rear side of the article to push the article, with its wrapper, beneath the presser plate 108. This will fold over the second side of the wrapper, as will be readily understood by.

reference to Fig. 16, the article being fed forward to a point immediately beneath forming levers 113. These forming levers, of which there are two, (see particularly Figs.

1, 2, 5 and 17), are pivotally mounted at 114 to a support 115, dependent from the upper head 103. The said forming levers 113 have inwardly projecting arms 116 carrying gear sectors in mesh with each other, so that the movements of the two said levers will be synchronous. One of the levers l13'is provided with another arm 117, said arm carrying an anti-friction roller 118 arranged to engage a cam surface 119 upon a bar 120. The cam bar 120 is carried by the support 115, but is arranged to have a relative Vertical movement with respect thereto, said cam bar'having a lateral projection 121 arranged to engage stationary abutments 122 upon the pedestal. or standard 21. A spring 123 tends to draw the levers together and to hold the cam follower roller 118 up against the face of the cam 119.

When the upper head 103 is moved downward, the leyer 113, being carried thereby, will be moved downward therewith, and the lower ends of said levers, being opposite the ends of the article to be wrapped and the overhanging portions of the wrapper, as will be seen more clearly by reference to Fig. 5 in which an article is shown in position beneath the forming levers and with a wrapper partially folded around same, will engage the wrapper ends to form a preliminary fold thereof, as will be seen by reference to Fig. 17, the spring 123 tending to draw the levers together so as to press the ends thereof against the ends of the article to press the fold of the wrapper tightly against same. Near the end of the downward movement of the levers the lateral projection 121 of the cam bar 120 will come into engagement with the lowermost abutment 122, whereby the same will be held stationary during continued downward movement of the levers, so as to rock the levers outward against the resistance of the spring 123. During the upward movement, therefore, of these parts, the levers will be held outward and clear of the ends of the article, and clear also of certain rotating folding members which will now be operated, and will not be free to move inward until they arrive near the completion of the upward movement thereof, when the projection 121 of the cam bar 120 will strike the upper abutment 122 to bring the lower portion of the cam face 119 opposite the roller 118, and then the levers will again be free to move inward as before.

After the ends of the wrapper have been operated upon by the forming levers 113 so as to form the first operation of the end folds, and the forming levers have been moved outward in the manner above set forth, rotary folding members 124, 124, will be rotated against the ends to turn over the rearward projecting flaps thereof. This operation is shown in Fig. 18 the said folding members appearing clearly also in Figs. 3 and 5. These folding members 124 are mounted, respectively, 011 shafts 125, 125, suitably journaled in the frame of the machine, said shafts provided attheir outer ends, respectively, with gear-wheels 126, 126. The said gearwheels 126 are in mesh, respectively, with gear-wheels 127, 127 upon an operating shaft 128, said operating shaft also journaled in bearings in the main frame. At its rear end, the shaft 128 is provided with a mutilated driving pinion 129 (see particularly Figs. 3, 4, 5 and 6), said mutilated driving pinion arranged to be engaged by a mutilated driving gear 130 upon the main shaft 2 of the machine.

The operating parts of the machine are so timed, that while this last operation was being performed, the reciprocating plate 13, and parts carried thereby, will have moved rearwardly, and the cam 51 will, through its connections, have acted upon the movable bar 35, so as to move it relatively rearward with respect to the stationary bar 32, to open the gripper member 36. At the rear of the gripper member, the bar 35 carries a dog 131, the said dog being pivoted to the bar inthe same manner as the gripper member 36 is pivoted thereto, and provided with a downwardly ex tending finger engaging the bar 32, also in a similar manner thereto. When the bar 35 is moved to open the gripper jaws, as aforesaid, the dog 131will also be rocked upon its support, so that the end face thereof will rise above the top surface of the bar 35, and with the parts in this position, will so rise at the rear of the partially wrapped article beneath the forming levers 113. The dog is shown in such position in Fig. 19 of the drawings, while in Fig. 2 the dog is shown in its other position, at rest in an opening in the said bar 35, with its forward end below the upper surface of the said bar. The next forward movement of the plate 13, and hence of the bars 32 and 35 and their co-related parts, will cause the dog 131 to engage the partially wrapped article beneath the forming levers 113, to push the same further forward beneath the presser-plate 108. 111 being thus pushed forward, the article is pushed between end presser plates (see particularly Figs. 1, 2 and 3), these plates being pressed toward each other by springs 136, backed by abutments 137. The rear shoulders of these end plates will act as cams or abutments to turn over the forward projecting [laps of the end portions of the wrapper as the article is advanced, and the pressure the plates will cause the folded end portions to press tightly against the article. So far the partially wrapped article is resting upon. a support 132, secured to the main frame of the machine, the downwardly projecting end portions lying in convergent ways located between tongues 133 and cam surfaces 134. The action of the cam surfaces 134 upon the advancing article will be to tuck the eX tremities of the folded wrapper under the artiele, so that the article so far wrapped will appear about as is shown in Fig. .24 of the drawings. The forward movement of the plate 13 is suflicient to feed the article thus wrapped, to a point immediately above the open end of a delivery chute 138, and immediately beneath a plunger 139. At this point the article will be solely supported by the said presser plates, having been moved coin pletely beyond the end of any bottom sup port. The article is now completely wrapped, so far as the first wrapping is concerned, and is in a position and condition ready to receive the label.

The labels are arranged in a pile in a suitable magazine 140, the same being removably supported by means of the bracket 141 to the main frame of the machine. The labels in the magazine rest upon a follower 142, said follower provided with a portion 143 constituting a feed nut, the same engaging with a vertical feed screw 144, ournaled in bearin s stationary with the magazine. The feed nut is provided with a ratchet wheel 145, with which a feed pawl 146 is arranged to engage. The pawl 146 is adjustably pivoted to an arm 147, secured to a rock shaft 148, upon which is also secured a lever 149 carrying a cam follower 150. The cam follower 15o rests against the face of the cam 15]. upon the main shaft 2 of the machine, and the said cam, in its revolution, will rock the shaft 113 to operate the feei'l pawl, and thus to give a step by step movement of rotation to the feed screw .144. This will slowly raise the follower 142 to lift the pile of labels, for the purpose of cinnpensating for the labels as they are removed, in the operation of the machine, and the adjustment between the pawl 146 and the arm 147 is intended for the purpose of compensating for varying fllli'linesses of the said labels. A spring 152 openates to rock th a shaft 143 against the action of the cam, and to hold the eam up against the cam face.

Suspended above the label magazine is a gum or paste tube 153, said gum or paste tube being suitably supported by means of n bracket 154 upon the upper head 103. .1 thumb screw 155 is preferably provided for the purpose of securing the tube 153 in plaee. so that it may be readily removed when desired.

At its foot, the tube 143 has secured to it a foot piece 156, said foot pieee carrying a valve 1.57, having a dependent stem 151 which protrudes through the bottom. there of. It will be understood that, upon the reciprocation of the head 103, asabove set forth, the paste tube 153 will also be l'ttllil'o cated, being moved dowi'iward from the po sition in which it is shown in the drawings l 1- ward the labels in the magazine, until, 'iinally. the stem 153 will engage the topmost labe and the valve will be brought to rest. slight continued downward move ment of the tube will open the valve and. a small quantity of paste or gum will flow through the valve opening from the tube to eill'eet a eonstanl but slight feed. of paste or gum to the valve stem and thus to the label when the said stem engages it. The label will thus be caused to stick to the stem v153 of the valve 157, and, upon the upward or return movement of the tube, the topmost label, which, it will be understood, .is extremely light in weight, will be lifted up into line with the jaws of the grippermembers 3 6 and 3-1. The parts of the machine will be so timed that. at this 111011161111, the gripper jaws will be open and moving toward the label, so that, when the jaws get to a position to grip the label, the label will be presented for that purpose.

As before explained, the moment the bar carrying the gripper members get to the foremost position in their reciproeation, the jaws will snap to a closed position by engagement of the cam piece 41 with the abutment 4i, and the label will be firmly gri 'iped thereby. Upon the return movement of the bars 32 and 35 with the plate 13, the label thus gripped will be carried rearwardly to the positien in which it is shown in Fig. 2, and directly above the open mouth of the delivery chute 138 beneath the wrapped article, held between the end presser plates 135 and in a line with the plunger 139. Upon the next downward movement of the upper head 103 the plunger 139 will be carried down and will engage the top of the article to force same downward upon the label held thus waiting in position, and then still further downward into a receiver 159 arranged at the receiving end of the delivery chute.

Cheek pieces 160 are arranged at the rear and front of the forward path of movement of the article above the receiver 159, so that, in being so forced downward, the label is given an initial fold, as is clearly shown in the diagram Fig. 21. The receiver 159 has a spring pressed front wall 161, so that the articles thus forced therein will be held laterally under yielding pressure. They are, at the same time, of course, supported by other articles which have gone before, after the first few articles have been delivered, and the delivery chute is filled up to this point. In forcing the article with the label thus partially folded around it downward, the upper edge of the article is caused to be brought about in line with the under'faces of folding plates 162, 163, the said folding plates being arranged to reciprocate in a path immediately above the said article, and, in their reciprocation, to fold the projecting sides of the label over the upper face of the wrapped article. When the article is pushed downward by the plunger as above described, both of the folding plates 162, 163 will be retracted so that the path of movement for the article will be clear, as shown in Fig. 21, but, immediately the article has been so pushed downward and the plunger 139 has been Withdrawn by the upward movement of the upper head 103, the forward folding plate 162 will be reciprooated above the article, as shown in Fig. 22, with the result that the front projecting portion of the label will be folded over. This plate 1.62 is reciprocated by means of a lever 164, which is secured to the rock shaft 148. This lever engages the said plate 162 and causes same to'move backward and forward to effect the first fold of the label every time the rock shaft 148 is moved by the above mentioned cam 151. This cam, therefore, is employed for the double purpose of operating the said first folder plate and the perpendicular feed for the label magazine. Directly this first fold has been completed, the second fold may be made by means of the second folding plate 163, which is engaged for this purpose by a lever 165, provided with a cam follower 166 in engagement with a cam 167 upon the main shaft of the machine. The cam 167 is timed to move the plate 163 forward at the right moment to complete the last fold of the label as the plate 162 recedes, and the end of the label thus folded over having been provided with amodicum of gum or paste, the last fold as to securely fasten the label fastened 011 and is in the receiving end of the delivery chute. Successive deliveries of successive articles will force the said articles down the delivery chute one on top of the other, from whence they may be removed as is desired. I have, however, provided means for removing the article from the said chute in batches of a predetermined number as follows: At the side of thechute, near the forward end thereof, is arranged a pusher 168, arranged to have a lateral movement across the chute to eject articles therefrom. The width of the pusher face is of a dimension suflicient to include the predetermined number of articles desired to be ejected. The pusher as a whole includes a slide 169 mounted in guideways 170, and the said pusher is normally held in a rest position in the said guideways, but may be given a lateral path of movement across the delivery chute when desired. The slideportion 169 is provided with an upwardly projecting lug or abutment 171, with which the moving portion of an operating member is adapted to engage.

The operating member comprises a reciprocating bar 172, said bar being given a constant movement of reciprocation for each revolution of the machine. The bar 172 is pivotally secured at its rear end to an arm 173, arranged upon a rock shaft 174, said rock shaft mounted in bearings 175, and provided with another arm 176 carrying a cam roller 177, which engages with the face of a crown cam 178. The crown cam 178 is mounted upon the main shaft 2 of the machine. At its forward end the reciprocating bar 172 rests upon an anti-friction roller 179, arranged at the end of an arm 180, secured upon a short shaft 181. Secured to the same shaft, and at about right angles thereto, is another arm 182, the end of which is arranged in the path of movement of the articles in the delivery chute. A spring 183 normally presses the arm 182 forward to lift the arm 180, and thus supports the end of the bar 172 at a predetermined height. The bar 172 is provided with a lateral projection 184, which, when the bar is so supported, will travel over the top of the abutment 171 in the reciprocation of the said bar. If the arm 180 be depressed by the forcing forward of the arm 182, by the forward movement of the articles in the chute. as the foremost article engages the said lever, the front end of the operating bar 172 will be allowed to drop to an extent suflicient to cause the lateral projection 184 to engage the abutment 171 in its reciprocation, and at such time, therefore, to move the pusher forward. Thus, when the delivery chute has been completely will) lilled, the engagement of the foremost article will operate to cause the rejection of a number of articles equal to the breadth of the pusher head. In the present drawings, in. order to save space, .l have shown the delivery chute as quite short, and the width of the pusher head as sullicient only to take in. two or three of the aricles, but it will be understood that in practice, this may be varied, and the ejecting device may conveniently eject twenty live, fifty, or more articles at a time. The slide 16$) provided with sec- 0nd abutment 185, aranged at the rear of the abutment 17]., and so located that after the pusher has been moved. forward, it will always be moved back again. by engagement of the lateral projection 184.. The abutment 185 is of such a height that the lateral projection 184; will always engage it, so that, even though the bar has been lifted, when the articles have been ejected from the chute, the rearward movement of the bar 172 will still effect the rearward movement of the pusher.

It is thought that the entire operation of themachine will be quite clear, from. the foregoing, but for the sake of additional clearness, attention is called to the following timing of the various parts: A complete reciprocation of the plate 13 with all parts carried thereby, is made during one half of revolution of the main shaft, and the said parts are held at rest during the other hall of the movement of the main shaft. in this movement, the lowermost article fronithe magazine 7 5 is pushed to a position beneath the plunger 7 6, while another article is pr shed from a point in line with the said plunger to a position beneath the "ermine levers H3, and. still another rticle is pushed from a point beneath the forming levers 113 to a position beneath the plunger 1 The firs t said article is acted upon by the pusher plate 29, the second by the forward end ofthe plate 13, and the third. by the dog 131, carried by the bar 353. During nearly all the time the plate 13 and corelated parts are operating, the overhead mechanism was held stationary, but the said. overhead mechanism given a complete re ciprocation, after the various articles have been deposited beneath the plungers 76 and 139 and the forming levers 113, such re "iprocation occupying a period of one-half of the revolution of the main shaft 2. By this means, three articles are operated upon simultaneously at each revolution of the machine. It will also be noticed that the feeding periods and the operating periods slightly overlap each other; that though each occupies a period of one-half a revolution. of the machine, these two periods do not maize up an entire revolution, but, in overlappi g each other, as above stated, include a short period, during which all the parts stated are at rest. This rest period is utilized for the purpose of carrying out other operations, so

sensor that at each revolution of the machine, a complete article is delivered, such article, du ring its passage through the machine, hit-ring received quite a large number of treatments. By the foregoing, much time is saved, and the machine will have a capacity of a large number of con'ipletely wrapped articles per minute.

The .niiachine is quite simple, considering the amount of work done, being, so far as l am. aware, considerably simpler than any other .i'nacl'iine designed for the same purpose, now on the market. Further, it will be noted that all the parts are very aerr-ssi ble, so that they may be readily cl aned, renewed or repaired. The overhead paris are all mounted. upon a single head 10S, and may be removed bodily, if desired, without the necessity of dismantling the othe. portions of t o mathine. Similarly, "the label magae zinc and its equivalent may be readil; moved, and the remainder of the Illit..llll( may be almost readily dismantled by die removal of but a few screws. in order that the overhead parts may be moved out of the way, if desired, without being actually re moved, l. have constructed the portion which I have described heretofore as the upper head 103 in two parts, one including a bracket 186, provided with a vertiral hub, which is directly mounted. upon the plunger rod 20, and with a horizontal hub 18?, and the other including a horizontal spindle 1M. mounted in the said hub 187. 'llhe plunger 76, forming levers 11?), plunger 113W, and

paste tube 153, are all suspended from ll t" spindle 1.88, so that by turning the said spindle in the hub 18?, all these parts may be swung clear, so as to permit entirely free a cess to be had to the remaining portion of the marhine. A set screw 1.85) is provided for locking the parts in t eir operative posit ion. the said set screw prt erably arr: vnged to engago a depression in the spindle 1248, to prevent accidental displacen'ient.
